There is now preparing, and will in a short time be
published, The Singing Book with Letters instead of notes,
with the bass to the tunes, correctly engraven on copper;
with some further and useful instructions, which will render
that little book still more acceptable and beneficial, to
all that have any regard for regular singing:  and will be
sold by Samuel Gerrish near the brick meeting house in
Cornhill, Boston.
